Neighborhood Disadvantage Predicts Delay in Care in Bilateral Breast Reduction.

Abstract

The Area Deprivation Index (ADI) is a validated quantifiable measure of neighborhood disadvantage and social determinants of health (SDoH). Higher percentiles in ADI correlate with the most disadvantaged neighborhoods: lower income, lower education, and less access to transportation. Using ADI, we aimed to investigate the impact of SDoH on bilateral breast reduction (BBR) complication rates. A retrospective study of BBR patients from 2015 to 2021 was conducted. Patient addresses were matched to ADI percentiles and grouped into most (top 80% ADI) and least disadvantaged. Multivariable regressions were used to compare postoperative treatment between groups and adjust for confounders. In total, 568 patients were analyzed and 47% were high ADI. Time-to-event analysis revealed a 155% (β = 2.55; CI, 1.87-3.48; P < 0.001) increase in time to presentation for treatment of wound-related complications among higher-deprivation patients compared to their lower-deprivation counterparts. This difference in time to presentation equated to approximately 3 days overall when comparing higher to lower deprivation patients; however, this difference between the groups increased to 12 days when comparing those who experienced wound-related complications beyond day 30. High deprivation was associated with increased delays to treatment after complications. More research is needed to determine the factors that impact postoperative courses among high ADI patients.
